signor to Reuge S.A., Sainte-Croix, Switzerland, a corporation of Switzerland Filed Apr. 11, 1963, Ser. No. 272,417 Claims priority, application Switzerland, Apr. 18, 1962, 4,747/62 3 Claims. (Cl. 280-1135) The present invention has for an object a ski safety attachment, comprising a stop member designed to hold in a removable manner the front end of the boot, this stop member being pivotally mounted on a supporting plate.

The attachment according to the invention is characterized in that it further includes a base plate designed to be fixed to the ski, and catching means at the front and at the back of the supporting plate to engage complementary parts of the base plate and thus permit the removable mounting of the stop member on the said base plate.

One aim of the invention is to permit skiers, in particular competition skiers possessing several pairs of skis, to take the stop members of one pair in order to adapt them to another pair.

Another aim is to facilitate the transport of one or several pairs of skis the stop members of which have been withdrawn, by securing them one against the other with the point always directed on the same side.

The accompanying drawing shows, by way of example, four embodiments of the attachment forming the object of the present invention.

FIG. 1 is a section of the first embodiment along line 11 of FIG. 2.

FIG. 2 is a view from below of FIG. 1.

FIG. 3 is a section of the second embodiment along line 33 of FIG. 4.

FIG. 4 is a view similar to FIG. 2.

FIG. 5 is a section of the third embodiment along line 55 of FIG. 6.

FIG. 6 is a view from below of this embodiment.

FIG. 7 is an end view of the fourth embodiment, in the direction of the arrow A of FIG. 9.

FIG. 8 is a plan view of a detail of FIG. 7.

FIG. 9 is a plan view of FIG. 7.

The safety attachment shown includes in a general way a stop member shown in dot and dash lines at 1 in FIG. 1 and designed to hold the front end of the boot. This stop member 1 i mounted on a threaded pivot 2 integral with a supporting plate 3 removably fixed to a base plate 4 itself screwed on the ski 5 by means of screws 6.

The base plate 4 is provided to this end with openings 6' directed along the axis 11 of the ski and the longitudinal edges of which are notched over about half the thickness of the plate 4. A small plate 4' (FIG. 1) pierced centrally in order to allow the passage of the screw 6 is provided with teeth designed to engage with those of the openings 6, the whole so as to be able to adjust the position of the stop member longitudinally relative to the ski.

The supporting plate 3 has on it rear side 7 an edge folded inwardly so as to constitute a hook 8 designed to catch the rear edge 9 of the base plate 4. A knurl-headed screw 10, actuated from outside, is carried by the front end of the supporting plate 3 and screws into a corresponding tapped hole 11 of the base plate 4. This plate 4 has under its rear edge 9 a clearance 12 to receive the end of the hook 8. In order to separate the supporting plate 3 from the base plate 4 it is sufficient to loosen the screw and to pull the plate 3 backwardly in order to bring out the hook 8 from the clearance 9.

In a modified embodiment, the lower surface of the stop member 1 exactly covers the supporting plate 3 and the pivot 2 is movable in a guiding groove provided in this plate when the stop member pivots in case of release of the end of the boot. In order to hold the stop member to the supporting plate, the pivot comprises to this end a head extending under this plate into a space provided between the latter and the base plate, the dimension of the pivot head being sufiicient to span the guiding groove. The screw 10 is then replaced by a screw with a countersunk head.

In the embodiment of FIGS. 3 and 4, the supporting plate 3' has on its rear side two tongues 13 designed to engage in two corresponding openings 14 provided in the rear side of the base plate 4'. These tongues are bent to permit their easy engagement in the openings 14 and their ends extend into a clearance of the plate 4 and hold the plate 3' vertically. In order to separate the plate 3' from the plate 4", one loosens the screw 10 then one swings the plate 3' rearwardly until the tongues 13 may be freed from the openings 14.

Instead of two tongues 13, two lugs might be provided engaging in corresponding notches disposed in the rear edge of the base plate. One could also' provide only one tongue 13 and a single lug engaging in a corresponding opening of the said base plate.

In the embodiment of FIGS. 5 and 6, the front end of the supporting plate 3" carries a hook 15 with a knucklejoint closing lever 16. This hook is designed to engage in a housing 17 provided in the front end of the base plate 4". The rear edge of the support plate 3" is similar to that of FIG. 1 and catches on the cleared edge 18 of the plate 4".

By opening the closing lever 16 one releases the hook 15 from the housing 17 and the plate 3" may be drawn backwardly to be separated from the base plate 4".

In the embodiment of FIGS. 7 to 9, the supporting plate 19 seen in plan in FIG. 9, comprises rear and front grooves 20, 21 designed to engage with rear and front flanges 22, 23 of a base plate 24 seen in plan in FIG. 8. The rear side 25 of the supporting plate 19 is closed so as to abut against the corresponding rear edge of the base plate 24. The screw 10 holds the front end of the plate 19 although this is not absolutely necessary.

In order to separate the plate 19 from the plate 24, it is made to slide by pulling it backwards until its grooves are freed simultaneously from the flanges of the plate 24.

In a modified embodiment, the supporting plate for the stop member could be fixed bayonet fashion on the base plate.

The advantages of the attachment described are the following:

(a) The stop member of which the releasing force has been adjusted in function of the weight and the technique of the skier, may be easily and rapidly adapted to different pairs of skis.

(b) The transport of several pairs of skis is facilitated because the skis may be attached one against the other and be much less cumbersome when the stop members have been withdrawn.

It is to be understood that the base plate of the embodiments shown in FIGS. 3 to 9 could also comprise means for adjusting its position longitudinally on the ski as is the case for the embodiment of FIGS. 1 and 2.

What I claim is:

1. Toe clamp for a safety ski binding comprising a base plate fixed to a ski, a supporting plate carrying a pivot, a block member pivoted on said pivot for engagement with the fore end of a ski boot, said supporting plate being of substantially the same dimensions and shape as said base plate, hooking members provided on the rear and fore edges of said supporting plate for removably securing it onto said base plate, and said base plate having recesses for receiving said hooking members.

2. Toe clamp for a safety ski binding according to claim 1 wherein said supporting plate is provided with a rear edge folded inwardly to form a hook to engage the rear edge of said base plate, said base plate having a shoulder near said rear edge to provide a clearance under said base plate to receive said hook.

3. Safety ski binding comprising a base plate fixed to a ski having a housing in the front end thereof, a supporting plate secured to said base plate, a stop member to hold removably the fore end of a boot, said stop member being pivoted on said supporting plate, hooking members located fore and aft upon said supporting plate which may be hooked in the corresponding portions of said base plate whereby said stop member is removably secured to said base plate, said hooking members comprising forwardly a hook with a knuckle-joint closing lever cooperating with said housing.
